Cubic Christmas Tree (OpenSCAD)

thingiverse

I discovered that QuanTom's "Futuristic Christmas Tree" was a really cool tealight LED candle cover for these festive days. I wanted to change its size (easy to do) and shape (not so easy), so I redesigned it with OpenSCAD. There are two boolean switches in the source file: HIDECANDLE and COVERBASE. HIDECANDLE shows or hides the candle in the preview window, allowing you to check that your tree design won't interfere with the tealight led candle. COVERBASE generates a 'sleeve' over the candle base if set. Then, there are some variables you can change: TreeIdx and Trees. Set TreeIdx from 1 to n, where n is the last tree description in the "Trees" descriptor vector. I provide six different trees here. The first two ones are larger and more like the original one designed by QuanTom. Take care to check the "CandleBD" value and adjust it to the external diameter of your LED candles. Usually, the external shell of these candles is slightly conical. If you use a value between the smaller and the larger candle diameter, then the generated 'sleeve' will lock itself over the candle base and the candle won't 'fall' into the printed tree if you push it (slightly). Merry Christmas to everyone!
